JOSEPH BROOKWAY, OF CAMBRIA, NEW YORK.

IM PROVEM ENT IN STRAW-CUTTERS.

Specification forming part of Letters Patent No. 48,649, dated July 1l, 1865.

To all whom it may concern Be it known that I, JOSEPH BRocKwAY, of Cambria, in the county of Niagara, in the State of New York, have invented new and useful Improvements for Cutting Straw, Hay, Stalks,

` variousgures.

Figure lis a plan. Fig. 2 is a side elevation; Fig. 4, perspective view. Figs. 3 and 5 are front elevations.

The nature of my invention consists in atcaching the cutting-knife to the lower end ofa pendulum, so that the swing of the pendulum will bring the edge of the cutting-knife to cut the straw obliquely, or by a drawing stroke, as the knife passes the throat ot'A the cutting-box in which the straw is placed. Further, the pendulum acts as a balance-wheel, giving force and momentum to the knif'e when in the act of cutting the straw, 85o. It also admits of using a very simple knife, oracradle-scythe can be used for a knife.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

At a in Figs.'2, 3,4, and 5 is an upright frame, to which the pendulum is hung at its upperl end, at b; or the pendulum may be hung to an upright post in a beam or to the side of any building, which may be preferable when made on a large scale and used as a stationary machine.

In Figs. 2, 4, and 5, at c, is seen the pendulum', or a triangular frame, hung by a. pin at b to theframe, (at its upper end,) with the cuttingknife l attached to the lower portion ofthe triangular pendulum-frame, sothat in pushing by the hand fin Fig. 4 the said cutting-knife is made to pass obliquely by the box E in Figs. 3 and 4, which contains the straw to be cut. The knife is then drawn back by the hand, as seen at f in Fig. 4, and is ready forfanother cut.

Fig. 1 is a ground plan, showing the strawhopper E, also the triangular frame c, colored green. Outside of this is a bar ofiron or wood, colored red,as seen in Figs. 1, 3, and 4, (marked g,) within which the pendulum slides, and is kept by said bar g close to the frame a, to secure a close cut of the knife to the box E. v

What I claim as my invention, and desire t0- secure by Letters Patent, is-

The attaching the knife to the lower part ot a pendulum or swinging frame, for the purposes as herein set forth.
